BACKGROUND AND AIMS The ventricular enlargement observed in children with chronically raised intracranial pressure (ICP) causes a secondary loss of brain tissue. In animal studies of hydrocephalus, programmed cell death (apoptosis) has been found as a major mechanism of neuronal injury. One of the regulators of the apoptotic cell death programme is the receptor mediated Fas/Fas ligand interacti...
The Fas ligand is predominantly expressed in activated T lymphocytes and is one of the major effector molecules of cytotoxic T lymphocytes and natural killer cells. Previously, we found excessive apoptosis of epithelial cells and infiltrating lymphocytes expressing Fas ligand mRNA in the lung tissue of bleomycin-induced pulmonary fibrosis in mice. Here we demonstrated that the administration of...
BACKGROUND There are limited reports on the role of the cell surface receptor Fas and its ligand molecule in mediating apoptosis during infection with the hepatitis C virus (HCV). OBJECTIVES The aims of this study were (1) to assess the susceptibility of the Fas antigen expressed on peripheral blood mononuclear cells to Fas ligand-induced-death in patients with chronic HCV infection and (2) t...
Clinical and genetic heterogeneity renders confirmation or exclusion of autoimmune lymphoproliferative syndrome difficult. To re-evaluate and improve the currently suggested diagnostic approach to patients with suspected FAS mutation, the most frequent cause of autoimmune lymphoproliferative syndrome, we prospectively determined 11 biomarkers in 163 patients with splenomegaly or lymphadenopathy...
It has been believed that the Fas expressed on human peripheral blood T cells (PBT) is nonfunctional, because these cells are insensitive to agonistic anti-Fas/Apo-1 mAbs that efficiently kill in vitro-activated T cells and many Fas-expressing cell lines. Here, we demonstrate that membrane-bound Fas ligand (FasL) kills both fresh and in vitro-activated PBT, indicating that the Fas expressed on ...
Background: Glaucoma is one of the most common causes of blindness and is usually associated with elevated intraocular pressure. In patients with primary open angle glau-coma the number of trabecular meshwork cells is decreased. Death of the trabecular meshwork cells may be a result of apoptosis. Objective: To investigate the aqueous humor levels of soluble Fas (sFas) and Fas-Ligand (sFasL) in ...
We report a soluble isoform of mouse Fas, which is generated by alternative splicing of Fas mRNA to a newly identified exon located between exons 2 and 3 of the previously published Fas sequence. This splicing event creates a novel Fas transcript, Fas beta, with the potential to encode a truncated form of the extracellular domain, termed Fas B. In vitro, P815 mastocytoma cells transfected with ...
